Known issues

The Migrate packages.config to PackageReference... option is not available in the right-click context menu

Issue

When a project is first opened, NuGet may not have initialized until a NuGet operation is performed. This causes the migration option to not show up in the right-click context menu on packages.config or References.

Run NuGet restore - Right-click on the solution node in the Solution Explorer and select Restore NuGet Packages

Build the project which also triggers NuGet restore

You should now be able to see the migration option. Note that this option is not supported and will not show up for ASP.NET and C++ project types.

This document summarizes the issues around that scenario, the plan for addressing them, and workarounds you can deploy with today's state of the tooling.
